Most valuable pumps

Might be safer though to slow down each pump if its target gets too full.

It's kind of like ants. Any individual ant only see what it's doing, and doesn't even understand that, but it does it. Together, you get a functioning system.

@@kindlinExactly! And you can take it a step further on humans. While we don’t necessarily work together in the end everyone functions as a giant system. We impact so many other people without even realizing and it doesn’t even take being famous! Any small social interaction we make affects people’s thoughts, even by a little, which makes them act and communicate with other people differently than they would’ve without interacting with you, which in turns affects more and more people. That’s the principle of the butterfly effect

It's an example of a dynamic system! Similar to fireflies slowly getting synced up with each other. You can read more about it in the book Sync by Steven Strogatz.

very modern machine

They had it for a long time but their first lego robotics kit was super expensive. It was like $500-700 IIRC. Way cheaper to buy actual electronics and have the kid learn how to do the real thing.

I remember getting that first mindstorms set you could program on your pc as a kid, it was cool but I was just lacking the knowledge to build something actually cool and inventive of course. I still have those electric parts somewhere, although I don't know what happened to the rest because I used to mix everything up after playing with a set for like a week, I think you know what I mean😂

@@thex6992I still have an NXT and an RCX, as well as the sets they came from and various other parts in a wheeled cart in my bedroom... I really loved them, back in the day when I had Windows machines. We never had anything like FIRST here, but I totally would have done _anything_ as a kid to get into something like that. I really loved the idea of Lego Mindstorms. I know there's some kind of open-source firmware for both that makes them run some dialect of C... but it seems like extremely capable microcontroller dev boards (and for a little more, far more powerful systems-on-a-chip able even to run regular OSes like Linux, thanks to the smartphone revolution) and accessories (motor controllers, sensors, etc.) have gotten so cheap it's almost more worthwhile to 3D print an enclosure for those than to try to hack my existing Mindstorms parts to do things... hmm... I keep looking at my little Lego and junk collection cart and my 3D printer and such and wishing I had the inspiration to build something, but the past few years I've been hit by a strange inability to commit myself (or more importantly, any resources) to any project that can't be proven 'the most practical/profitable way to accomplish the objective' ahead of time. I guess I feel generally guilty or wasteful, somehow. I really wish I could get that creativity I used to have back... Maybe I should spend some time just playing with the Lego parts again...

wth

It's so impressive that technology has advanced so far that we can animate every single drop of water by hand!

This whole channel is satisfying 😊

shut up

THE VID IS 9/11 SECONDS LONG

As far as toys go, it's a marvel of engineering.

It looks like the only one let down by Lego's water tightness was the centrifugal

It's also suitable for more viscous mediums than water 💩

NASA

huh. no wonder that sounds very similar to the machines the doctors use to pump medicine into my veins.

I use it in in a soap dispenser

IT LEGO COOKING

WHAT ARE THEY GONNA COOK NOW 🔥🔥🔥🔥🔥🔥

Sorta both, it selects from a set of speeds based on water level

Proportional in discrete steps, so both. I wonder if it's possible to get an analog level and create PID control for them though?

I can't put my finger on it, but there's something appealing about the way it works.

@@drworm5007 It's the way pumpjacks move oil but its horizontal instead of vertical

It might be your favorite now but when you make one and use it in real life and have it working reliably the valves will make you go crazy, they always cause problems, they're expensive to replace, they're only ideal for clean water without anything like sand, leaves etc. inside of it and they need back pressure so it's ideal to run them 24/7, not really a ON/OFF design like the centrifugal pump, gear pump or the screw pump

And then the cinematography and editing - also fantastic!

yeah absolutely! I'm a chemical process operator, so i work with pumps like this on a daily basis, so it's really cool to see someone make them with legos! it's amazing how you can make advanced machines with such simple blocks

Yeah dude, it's like he based his creations on designs that were/are already in use for hundreds of years all over the world! Who would've thought they actually work?

@@arcuz7862 Stop.

@@arcuz7862 why are being like that ? did you had a bad day ?

Not in this case; it only improves flow rates by reducing loss/spillage.

​@@JustinShaedo uh, no? Putting it in a pipe effectively increases the scoop size dramatically.

Through all cases we have here so far, I wish they had more accessible Lego bricks that could fulfill these thoughts

Yes, but I don't think there would have been a way to make that with lego (although I really appreciate you sharing the information)

@@SqueakyNeb Yes! You're generally right: putting an Archimedes screw in a pipe might increase the effective scoop size and thus transport rate if: 1)The edges of the scoop were (too) shallow (thus reducing overflow) 2) The end was immersed deep enough in the water; so that the 'scoop' can completely fill. 3) The spirals are tight enough relative to the angle of elevation. The scoop is not immersed deep enough, and the spirals are too loose such that in this case, enclosing it won't improve transport rates at all. Have a look at some of the images of Archimedes screws, see how they have tight spirals and the ends are submerged deep enough to take a full scoop? So we whilst actually agree on the principles here, the application differs a bit in this case... If you're starting out on learning engineering principles, respect to you, and luck on your journey, it's complicated but worth it!

It's interesting to see that the water wheel was shifting the most water.

​@@penfold7800 actually the gear pump was by far the most effective. Like the design too.

@@penfold7800 Other pumps lack seals which doesn't help

@@penfold7800 The water wheel had 22ml/s flow rate while the centrifugal pump and gear pump both had 32ml/s flow rate, not only that the water wheel is not even a pump (at least not the way he did it) and it sucks. Not only does the water wheel need 10 or 20 times more torque to do the same work depending on the wheel diameter it will also always be 10 times bigger to reach the same flow rate and to make things even worse, for the water wheel to be a pump it would need to get the water higher than the highest point of the pump, which it can't, while the other pumps are capable of at least 1 meter height if it's just the LEGO one that he made. The real centrifugal pumps are able to pump the water from 5 to 41 meters of height while the gear pumps are the same as centrifugal ones but better because they can create a lot higher amounts of pressure, that's why they are used in some hydraulic pumps which need to actually push some weight and not just pump the water. The real water wheels often require something like a river to spin the wheel which either uses buckets if you want to just get the water out of the river or if you want it to pump the water above the river it powers a piston pump, centrifugal pump or a different pump designs not shown in this video.

@@CreeplayEU centrifugal pumps r unbelievable space efficient for the massive amount of water they can move quickly, downside is they aren’t very energy efficient in their operation

Bro why

Oh my god that montage at the end is to die for

Editing for high functioning people helps nobody else. They already know then answers. those who might want to learn whats happening find the speed of this inaccessible!

@@Mike-tv9rk Are you serious, Mike? I mean... are you really, really serious? Because, man... this is outstanding.

@@Mike-tv9rk Just lower the speed then

CHINESE DINNER 🍽

​@@DieselGloves Yum yum

Piston pump was by far the coolest one

2:47 just so we can all go back and re-appreciate the engineering.

I'm amazed that it worked so vell without any mechanical synchronization with piston cycles.

Ayy someone else with perfect pitch

Each one of these pumps has pros and cons in real world applications (well not every pump per se, but you get the idea). A peristaltic pump is mandatory if you want to pump liquid without the risk of contaminating said liquid (for instance, for medical reasons) A centrifugal pump offers a good balance of head pressure, with a relatively small number of moving parts, paking it quite reliable, and cheap to produce External gear pumps can have a lot of flow rate, but the head pressure is determined by the radius of the gears, it's actually very impractical in real life. Piston pumps are pretty efficient at generating even more head pressure, most of the time you see those pumps as "membrane" pumps, which work in a similar fashion, except that instead of a piston, it's actually a membrane that is moved back and forth, either electromagnetically (think like a speaker for instance) or using pneumatics.

​@@Dogeek gear pumps aren't impractical, they're used all the time for like oils and in your engine and stuff.

@@Dogeek Thanks for all of that info! Very interesting.

​@@Dogeek To echo an above commenter, external gear pumps are brilliant if you need to precisely measure the flow rate of the liquid you're pumping. They're used when mixing resins for composite manufacturing

Yeah, but when the ones at work get even the slightest hint of wear they just stop lol

​@@selske23 good thing lego can be taken apart

You can't get continuous flow from an Achmedes Screw pump unless you (pick one) enclose the screw and spin fast, use a less viscous fluid than water, remove gravity. Starting submerged will not create continuous flow.

Pov:you don't know how everthing works and didnt expect that lego is confusing and complicated

It seems the impeller style pump has the largest flow rate. Though im sure it wouldnt produce as much pressure as some of the other designs. Granted, with legos like this you really cant get a very good seal which would really hurt any ability to build much pressure

@@tjziegler8823The one with the highest pressure though by far is the peristaltic pump, since it directly pushes the fluid through a completely fluid-tight passage (hose).

Yeah but it’s not meant to be efficient but satisfying it never had a productive purpose

@@Dankku_w what?

wait what i am the thrid?????

Hehe I'm early

Added challenge code pid controllers for all of them instead

Given they all use the same electric motor, it's the centrifugal one.
